We should believe and confess that Jesus is the messiah. In all our physical and spiritual ailments, we can ask Jesus for mercy. Jesus is victorious over evil. Jesus may do his work through us publicly or privately. We should not disobey Jesus. Our personal testimonies should not distract from the work of Christ but enhance his message of salvation.The testimony should always be for the good of the gospel. Sin robs us of seeing and speaking truth. Jesus restores our vision to clarity and gives us a voice of righteousness. Even today enemies of Christ will claim his work to be evil. We must readily be prepared to refute such accusations.
The two blind men called Jesus Son of David, a title of the Messiah. They do not ask for healing, but for mercy. Jesus went indoors to perform this healing in secret. Faith was required: Jesus asked if they believed in his ability to heal them. Jesus touched their eyes, so they would know he was the source of their healing. The restoration of their sight verified their faith. After Jesus warned them not to tell anyone. The two men could not contain themselves, and told everyone about the miracle. While their joy was understandable, they should not have disobeyed Jesus.
A demon-possessed man was brought to Jesus. This miracle was performed in public. Jesus gave the man his voice back. Christ may have chosen to perform this miracle in front of the crowd to demonstrate his victory over evil. While the crowd was amazed, the purpose of Christ was not to amaze the crowd. The miracles of the Lord were a proof to his divinity, but his true mission was salvation. Hence, some healings were done privately, as in the case of two blind men. The Pharisees could say nothing about the blind men being healed as they did not witness it, but the public healing of the mute gave the Pharisees the opportunity to claim the work of Jesus was evil in attempt to hinder his true message.
